The goal is to publish the highest quality research regarding applied mathematics and energy systems that cover all the engineering areas for solving complex and current issues. The Journal selects the articles based on high-quality standards, and it is published by the Universidad Tecnológica de Bolívar.</p> <p><strong>ISSN:</strong> 2745-0120 (<em>Online</em>)</p> <p><a href="http://creativecommons.org/licenses/by/4.0/" rel="license"><img src="https://i.creativecommons.org/l/by/4.0/88x31.png" alt="Licencia Creative Commons"></a></p> https://revistas.utb.edu.co/tesea/article/view/466 Methodology for characterization and planning of electricity demand in an isolated zone: Mitú Approach 2022-09-05T14:43:44+00:00 Santiago Bedoya Sánchez sabedoyasa@unal.edu.co Juan Felipe García Franco jufgarciafr@unal.edu.co Jairo Pineda Agudelo jpinedaa@unal.edu.co Cesar Arango Lemoine carangol@unal.edu.co Sandra X Carvajal Quintero sxcarvajalq@unal.edu.co <p>This paper aims a model for the characterization and planning of electricity demand in isolated networks when there is no information from the measurement system, a typical scenario in the Colombian Non-Interconnected Zone. This research is based on Arvidson method of the publication entitled: "Diversified demand method of estimating residential distribution transformer loads". This study proposes consumption indices for typical household appliances based on a statistical analysis of load censuses. Then, a timely contrast is made between the curves of the Arvidson study and the generation curves of the isolated network because there is no direct measurement in the end-users and by macrometers associated with the transformers. With this information, we proceed to complement the validated Arvidson curve with its own index; this index allows the proposed curve to be readjusted to a similar curve, per unit, with the generation profile. The main contribution is to propose a new factor, in order to, contextualizes and diversifies the Arvidson method to specific case studies to building daily electricity demand and diversified demand curves as tools for planning the electrical system and managing the electrical infrastructure.</p> 2022-09-05T00:00:00+00:00 Copyright (c) 2022 Santiago Bedoya Sánchez, Juan Felipe García Franco, Jairo Pineda Agudelo, Cesar Arango Lemoine, Sandra X Carvajal Quintero https://revistas.utb.edu.co/tesea/article/view/442 Visualization Proposal for Power System Control Rooms Based on Situational Awareness 2022-08-18T02:56:24+00:00 Daniel Betancur daniel.betancurtr@upb.edu.co Eros David Escobar david.escobarc@upb.edu.co Anderson Quintero anderson.quintero@upb.edu.co Jorge Wilson González jorgew.gonzalez@upb.edu.co Gabriel Jaime López gabriel.lopez@upb.edu.co Idi Amin Isaac idi.isaac@upb.edu.co <p>Due to the increasing size of electric power systems and its monitoring and operation needs, people at control rooms face complex situations, analyzing great amounts of information, protocols, operation states, alarms, and control parameters. Additionally, new renewable energy sources data is taking its place nowadays, hindering the process of quickly reading and interpreting information. This is known as the loss of Situational Awareness, SA, of system operators. This work presents proposals for displaying useful information in control rooms and visualization techniques to support accurate SA. Grid data displays, maps, trending graphics, lists, bars graphics, table plots, hierarchical levels, proximity regions, and connections are also proposed and analyzed, presenting an application case in a microgrid control room.</p> 2022-07-27T00:00:00+00:00 Copyright (c) 2022 Daniel Betancur, Eros David Escobar, Anderson Quintero, Jorge Wilson González, Gabriel Jaime López, Idi Amin Isaac
